Fix milliseconds for song initialization

This PR adds a miliseconds to seconds conversion for song Initialization from missing data.

Related Issue

Fixes #2021

Motivation and Context

For the calculation of best match, we calculate the duration differences which both have to be in the same scale where as for some songs it is milliseconds and seconds. This PR ensures that we divide the duration_ms by 1000 to convert to seconds

How Has This Been Tested?

Tests were completed based on the song list defined in #2021
